Blanking Circuit for a Magnetic Electron Multiplier in a Time-of-Flight Mass Spectrometer

Abstract

A blanking generator has been developed for use with a magnetic electron multiplier in a time‐of‐flight mass spectrometer. By blanking out superfluous portions of the mass spectrum, non‐linearity in the electron multiplier is minimized, gain is increased, and dirtying of the dynode strip is retarded.
